Muncamake yamakuru yamakuru agezweho, optique ya fibre itumanaho ifata umwanya wiganje.Hamwe no kwiyongera kwurusobe hamwe no kongera ubushobozi bwitumanaho, kunoza imiyoboro yitumanaho nabyo ni iterambere byanze bikunze.Module nzizamenya ibimenyetso bya optoelectronic mumiyoboro yitumanaho.Guhindura nikimwe mubice byingenzi bigize itumanaho rya optique.Ariko, mubisanzwe tuvuga kubijyanye na optique.None, ni ibihe bipimo bya modul optique?

Nyuma yimyaka yiterambere, modul optique yahinduye cyane uburyo bwo gupakira.SFP, GBIC, XFP, Xenpak, X2, 1X9, SFF, 200 / 3000pin, XPAK, QAFP28, nibindi byose ni ubwoko bwo gupakira module;mugihe umuvuduko muke, 100M, Gigabit, 2.5G, 4.25G, 4.9G, 6G, 8G, 10G, 40G, 100G, 200G ndetse na 400G ni igipimo cyo kohereza modul optique.
Usibye ibipimo byavuzwe haruguru bisanzwe bya optique, hari ibi bikurikira:

1. Uburebure bwo hagati
Igice cyuburebure bwikigo ni nanometero (nm), kuri ubu hari ubwoko butatu bwingenzi:
1) 850nm (MM, uburyo bwinshi, igiciro gito ariko intera yohereza, muri rusange 500m yohereza);
2) 1310nm (SM, uburyo bumwe, igihombo kinini ariko gutatana gato mugihe cyo kohereza, mubisanzwe bikoreshwa mugukwirakwiza muri 40km);
3) 1550nm (SM, uburyo bumwe, igihombo gito ariko gutatana kwinshi mugihe cyo kohereza, mubisanzwe bikoreshwa mugukwirakwiza intera ndende hejuru ya 40km, kandi kure cyane birashobora kwanduzwa bitaziguye nta rezo ya 120km).

2. Intera yoherejwe
Intera yoherejwe yerekana intera ibimenyetso bya optique bishobora koherezwa muburyo butaziguye.Igice ni kilometero (nanone cyitwa kilometero, km).Module nziza isanzwe ifite ibisobanuro bikurikira: uburyo bwinshi 550m, uburyo bumwe 15km, 40km, 80km, 120km, nibindi Tegereza.

3. Gutakaza no gutatanya: Byombi bigira ingaruka cyane cyane ku ntera yoherejwe ya module optique.Mubisanzwe, igihombo cyo guhuza kibarwa kuri 0.35dBm / km kuri module ya optique ya 1310nm, naho igihombo gihuza kibarwa kuri 0.20dBm / km kuri module ya optique ya 1550nm, kandi agaciro ko gutatanya kubarwa Biragoye cyane, mubisanzwe kubisobanuro gusa;

4. Gutakaza no gutatanya chromatic: Ibi bipimo byombi bikoreshwa cyane mugusobanura intera ihererekanya ryibicuruzwa.Imbaraga zo gukwirakwiza optique no kwakira sensibilité ya modulike ya optique yuburebure butandukanye, igipimo cyogukwirakwiza nintera yoherejwe bizaba bitandukanye;

5. Icyiciro cya Laser: Kugeza ubu, laseri ikoreshwa cyane ni FP na DFB.Ibikoresho bya semiconductor nibikoresho bya resonator byombi biratandukanye.Lazeri ya DFB ihenze kandi ikoreshwa cyane muburyo bwa optique hamwe nintera yohereza ibirometero birenga 40km;mugihe laseri ya FP ihendutse, Mubisanzwe ikoreshwa muburyo bwa optique hamwe nintera yohereza munsi ya 40km.

6. Optical fibre interface: SFP optique modules zose ni LC intera, moderi ya GBIC optique yose ni SC interfeque, naho izindi interineti zirimo FC na ST, nibindi.;

7. Ubuzima bwa serivisi ya module optique: amahame mpuzamahanga amwe, amasaha 7 × 24 yumurimo udahagarara kumasaha 50.000 (ahwanye nimyaka 5);

8. Ibidukikije: Ubushyuhe bwakazi: 0 ~ + 70 ℃;Ubushyuhe bwo kubika: -45 ~ + 80 ℃;Umuvuduko w'akazi: 3.3V;Urwego rw'akazi: TTL.
